ODONNELL, or NORWOOD, OHIO LYNN, MASSACHUSETTS, A con AssIeNoR T PARco' SPECIALTY 00., or PonA'TIon or MASSACHUSETTS COATED STRIP PROCESS OF COATING STRIPS Application filed February 11, 1928. Serial No. 253,701.

My invention relates broadly to processes of coating strips and specifically to partially coated strips and processes of coating textile and fabric strips with a cementitious coatin It is the object of my invention to coat textile or fabric ribbons with strips of cementitious coating which extend only partway across the width of the strips. In In copending application, Serial No: 253,700, filed Feb. 11, 1928, I have disclosed a novel process for applying French binding to shoes. F 01 use in this process I require French binding ribbons which have a strip uncoated and a strip coated with cementitious material which become softened and adhesive with the application of heat. The uncoated portion of the ribbon is stitched to the shoe, and the coated edge heated and turned over and cemented down to form a decorative edge around the shoe or parts thereof. There are many different formulas for the manufacture of a cementitious coating which may be applied in liquid form, which will then dry rapidly, and which may then be again rendered adhesive by the application of heat. I do not wish to limit myself to the use of any particular cementitious material, my-

claim to invention lying essentially in the manner of application and the method by which I guide and align the strips during the coating process. I j

Referring to the drawings in which I have illustrated diagrammatically suitable apparatus for carrying out my coating process:

Generally indicated at 1 I have shown the framework of the spool support on which the spools 2 carrying the strip material 3 to be coated are supported. The units may consist of as'many spools of ribbon as it is desired to coat. The ribbon strips are individually guided through apertures 4 in the front of the frame work from which they pass to the guiding slots 5 in the guide plate 6 which is supported substantiall in horizontal alignment With the feeding device which provides a continuous feed for the rib- Supported within the frame in alignmentv with the guiding slots are, the feed rollers 7 which are preferably rubber faced, and which are journaled with their axes parallel to the length of the guiding slots at their discharge side. It is important that the axes of the feed rollers be carefully set so that the rollers will pull the ribbons directly in the direction of their length as otherwise the predetermined positions of the ribbons might be disturbed during the feeding operation. As backing for the ribbon strips to prevent the accumulation of hardened cement on the table, I have provided a web of paper 8 which may be fed along under the overlapped ribbons in any desired way.

It should be noted that the lowest guiding slot 5 for the lower ribbon extends further to the left as indicated in Figure 2 than the guiding slot above it, and the slot above is likewise extended farther to the left than the one above it. This results in the guiding of the ribbons in an overlapped relationship with an area of each ribbon exposed excepting the uppermost ribbon. bon isentirely exposed, but as it is usually made of some material which is required to becoated throughout the entire extent of its upper surface no waste is caused.

I have diagrammatically indicated at 9 a spraying nozzle with which the cement is applied as a liquid to the exposed parts 10 of the ribbons. The cement might be applied, however, in pulverulent form, and the powder subsequently heated to cause it to penetrate into the body of the ribbons. I have further shown the guides 10 which serve to prevent the smudging of the table by the sprayed The upper ribcement, and which may also be used as guides.

The ribbons coated as indicated at 11 with a strip of cement rapidly dry, so that by the time the ribbons reach the opposite-end of the table the tape or ribbons may be wound up on the spools 12.

t The selvedge edge French binding is stitched with the cement coated'band dry and non-adhesive. By applying heat to the binding strip it will readily become plastic, and when turned down along a line extending along the inner edge of that portion which is coated with cement, the coated portion may be pressed a ainst the surface of a 15 leather strip and ma e to adhere firmly in position.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

2 1. The process of partially coating webs of French binding with heat plastic cement, which comprises guiding and pulling a plurality of webs of binding in overlapping rela tion one to another ina direction in alignment with the length of the webs, and while so overlapped coating the exposed portions of the webs with a cementitious material.

2. The process of partially coating webs of French binding with heat plastic cement,

which comprises guiding a plurality of webs into overalpping relation and pulling them together in the direction of the length of the webs, and applying a heat plastic cement to exposed portions of the webs.

3. The process of preparing partially coated binding tapes which comprises guiding and pulling a plurality of webs into longitudinal overlapping relation with each other, and while so overlapped applying a coating of heat plastic cementitious material to the exposed portions of the webs.

4. The process of preparing partially coated binding tapes which involves the employment of coating means for applying cementitious material to the tapes, said process comprising the disposition of a plurality of elongate strips with their margins in overlapping relation with each other, drawing the strips taut, and while so disposed employing the coating means to apply cementitious material to the exposed portions of the strips (luring relative movement between the coating means and strips longitudinally of the extent of the strips.
